not going to happen, the party's platform moves further from libertarianism and gets more more statist every election cycle.

i can forsee the the republican party perhaps fracturing, or splitting. we are starting to see that already. We have the establisment republicans that are progressive/ big governments-lite, and then you have the tea party types and the libertarian wings of the party. the latter groups are genuinelly for limited constituional government, the former part of the republican party as different from the democratic party as many people think. the last 4 years there has sort of been a clash within the republican party, of where its member want it to go.

but as for libertarianism gaining ground within the democratic party. not a chance, there's a greater probability of a 3rd party playing a major part in a presidential election than the DNC getting libertarians

They aren't.

If political beliefs are a circle, then libertarians are the opposite of moderates.  Perpendicular to those and opposite of each other are progressive and conservative.

Right now, conservatives are being pulled toward liberalism, mainly because of the Libertarian views on government and taxes.  Good for Libertarians, bad for Republicans.  The Tea Party is the catalyst for this, as they're a driving force behind the far more conservative views in the Republican hemisphere right now.  But ultimately, most Republicans would eschew the social liberalism of true Libertarians. 

My sister and brother in-law agree on regulations, taxes, and big government but when it comes to abortion, and gay marriage, no.   

A better example would have been gay-marriage or drug legalization. Abortion is quite a controversial topic among libertarians with almost a 50/50 split. 

The two-party system doesn't allow for splits. Just shifts in paradigms. This election cycle has shown a more libertarian Republican house, and with some work we can have a libertarian Republican senate. After the Bush era, and the failure of Obama's "promises" there has been a shift among the general public toward libertarianism of some extent (at least 1/3rd of the U.S population according to polls.) As for the democratic party, once the republican establishment falls (which it is currently) so will it's twin the the democratic party. You'll see more influence from both left-wing libertarians and with the common interests right-wing libertarians. Overall we'll she a shift toward the right (smaller government) because it's necessary for the left-winged libertarians to reach their goals. 

Both think Obama sucks.

The difference is that one thinks he sucks simply because he's a Democract.  The other thinks he sucks because of his issues/reversal on issues.

No, both conservatives and libertarians think he sucks for many reasons, not just for being a liberal. Even liberals have become disenchanted with Obama.

It was a joke about the average Republican.

I think instead that we're going to have a Populist/Progressive split, similar to the turn or so of the 20th century, where the social conservatives are going to ally with Big Labor, we'll see a split in the African American community, and libertarians will have certain planks prominently positioned on both sides (though both sides will still have stuff libertarians hate, their issues will move up in the pecking order).

I was agree to some degree with the original video.  Libertarians believe there is a need for at least SOME government, while anarchists want none.  Because of this, the nature of the debate is different and focus.  A major reason for this, is to try to debate whether or not there is a need for any government gets to be pretty lengthy and has more fundamental issues.  And here, it doesn't relate to whether or not Libertarians and Conservatives are the same thing.  That is why I had been trying to position away.  I would say, it is worth discussing, but please start it in another thread.  I definitely would like to see a Libertarian debate an Anarchist, which would put the Libertarian in the big government role in comparison.
