There's nothing difficult about voting in the US. Some people want to make the laws so lax, people can vote twice (thus helping certain politicians and their policies).

I've worked US polls before. They are clean, fair, and easy to register/vote in (at least from my time working them)... Unless you are trying to subvert voting, the ID/access laws are a good measure to prevent fraud. 

This means you would vote for the devil aswell.
You americans so "smart".

It was easy for me too.  I brought my voter registration card and of course had a license with me.  Took about 5 mins to early vote while they looked at my information and had me sign my name.  The only problem is sometimes Governors tell their Secretary of State to do excessive voter purges which Katherine Harris is the most perfect example of doing.

"In 1994 Harris was noted for the most expensive campaign for the Florida Senate to date, winning her seat that year in her entry into electoral politics. As Secretary of State of Florida, she conducted a purge of voter rolls, which was found to have dropped numerous eligible voters shortly before the 2000 presidential election. That year Harris gained national attention for her role in the Florida election recount, certifying George W. Bush's narrow victory over Al Gore and awarding him the Florida electors, which gained him the national election."

Oddly enough the only known case so far this election was a woman who voted for Trump twice in Iowa.  She had to get bailed out on a $5,000 bond and faces up to 5 years in prison.  That kind of penalty usually prevents most people from trying probably and if they didn't know then they will probably find out.

A Des Moines woman has been charged with Election Misconduct, a Class D felony, after allegedly voting twice for GOP presidential nominee Donald Trump. Terri Rote says she was afraid her first ballot for Trump would be changed to a vote for Democratic candidate Hillary Clinton.

"I wasn't planning on doing it twice, it was a spur of the moment," says Rote.* "The polls are rigged."

But Polk County Attorney John Sarcone says voter fraud in Iowa is very rare, which is evidence that Iowa’s election system is secure.

"I think in the 25-plus years that I've been doing this job, this maybe the third [time] we've had some irregularity that's resulted in a criminal charge," says Sarcone. "People aren’t voting more than once. And if they do, or attempt to do it, they will get caught because there are safeguards in place....We want everybody to exercise their right to vote, but only once."

Rote was released from jail on Friday on a $5,000 bond. If convicted, she faces up to five years in prison.

And that's precisely why we need good, tough, fair ID laws in place.
