Then perhaps you can be specific. In your opinion, what specifically has the GOP 'screwed up'?
What haven't they screwed up is the better question?
War on Drugs? Oh yup, that $30 billion a year to go after pot smokers.
Supply Side Economics otherwise known as Reaganomics which helped kick start the current downturn we're in.
Bush 41 putting U.S troops in Iraq in 1991 which ended up having Osama Bin Laden attack us in 2001.
Reagan trading arms to Iran to kill Iraqis and exchange for hostages.
Reagan giving arms and aid to Saddam Hussein to go and kill Iranians (Saddam wasn't too pleased with us when he found out what we were doing with Iran).
Non-Existent policies on Alternative Energy, they may not believe in global warming but SOMETHING needs to be done about our drug addiction to foreign oil. Doubtful anything will happen under the GOP with people like Bush who's first visitors to the White House were ExxonMobil among others.
Dividing this country by making a big issue out of Gay Marriage for no other then being a mere puppet for the Ultra Christian faction of the Republican Party. There is no economic or logical reason to keep Gay Marriage illegal; only because religion is it kept banned.
Seems the GOP doesn't believe in the "Government and Religion seperated" mantra.
Their odd fixation with wanting abortions banned because it's killing people but wanting the Death Penalty because it kills people.
Against all sorts of gun control (even the sane kind).
NCLB being supported by them highly but then underfunded by them.
The teaching of Creationism and Organized Prayer in school (once again, see above for the mantra they refuse to follow). Creationism is not science and quite obvious why Organized Prayer is bad.
I could go on really.
