This is an mid-term election year. A number of state governorships, every House seat and a third of Senate seats.
As of now. The Democrats will be winning control of the House and narrowing the Senate (likely outcome a tie) lead of the Republicans.
The Democrats will attempt to thwart Bush at every turn, undermine the effort against Islamism and other foes. Will eliminate the 2003 tax cuts and turn the knife in Entitlement Reform damaging the economy. Bush will not be impeached despite hopes and dreams of the Left.
Hillary Clinton will win the Democratic nomination in 2008 if she desire it. She cannot be stopped. John McCain will never gain the Republican nomination as long as he continues to stab them in the back for popularity. (Even though, if anyone says they "like McCain" they unkowningly mean they "like Bush" as their policy positions are all the same.) Rudy Guiliani is the current frontrunner, and one hopes, the nominee. If he is, he will win New York from Hillary and with it the election. (Hillary cannot win solidly red states.) If the Republicans choose Mitt Romney or most other "presidental" Republicans they will have a tough time defeating the most powerful politican in the nation.
The Democratic Party stands for nothing but power and doing whatever it takes to win. The Republican Party no longer stands for anything, the Reagan Revolution died with George H.W. Bush in 1990, the Gingrich Revolution died when they overindulged on Clinton and perks, and the George W. Bush killed the Bush Revolution when he gave up on the Bush Doctrine and Social Security Reform.
A sane, rational, intelligent person can't vote for the Democratic Party and doesn't want to reward the Republicans for simply not being Democrats.
If John Stewart and Stephen Colbert ran though, they'd have my vote for sure.
Which is sad, almost as sad as the probability they would recieve a significant percentage of the vote.
