He has to get a Republican majority through this year's mid-term elections.
There is no telling what the Dems will do if they gain control of one or both houses of congress.
Well, for starters, pull the troops out of Iraq and hand it over to the islamists, repeal the tax cuts, block any border fence, pass an amnesty program, block any pro-life SCOTUS nominee - Roe v. Wade stays on the books, and impeach President Bush. And it will be a very long time before we ever again see a Republican majority.
I hope all the "conservatives" on FR gleefully announcing they will stay home in November understand exactly what they are voting for.
