No they won't. Withdrawal will be far more complicated than you imagine. No move will be without political risk; every move will be scrutinized severely. Winning the Dem base will not translate into wider success among the Amercian voting public. The UN doesn't vote, and doesn't matter.
The economy will be booming, . . .
Only if the tax cuts are made permanent. A tax increase will depress it, shut it down--especially if spending programs are not curtailed.
The Republicans have never effectively resisted anything in the Senate and with a Dem in the Whitehouse
Republicans have never had this level of control with a Dem in the White House. Not in recent history, anyway.
Liberalism has been discredited. It is on its downhill slide. Clinton was sly enough to realize this, which is why he moved to the right. Apart from Lieberman (who has no hope) and perhaps Clark (who has almost no hope), none of the current crop of Dem presidential hopefuls has any ability let alone any inclination to move to the right.
I must modify the last comment. Screamin' Dean is a notorious cheapstake. He is likely to control spending--not because he is admires conservative values, but because he's a cheapskate. But he really has no hope either.
Any Dem who wins this fall will expereince the most feckless and frustrating term in power since Carter.
And Carter's wan, failed administration set the stage for a mighty Reagan victory.
You too easily forget the Republican Revolution in 1994. The Republican's had a true mandate. Within a year, the fiscal conservatives were carping about no balanced budget amendment. The NRA group was all hot a bothered about no assault weapons ban repeal. The Christian Coalition was withholding support because abortion hadn't been overturned. When the government shutdown hit, the conservative power groups stayed on the sideline because of all their single issue pet peeves. The Congressional Republicans got hung out to dry and took a beating. It was easy to blame on Newt being too arrogant, on the Republicans being too overreaching or that they misread the popular stance. The truth is conservatives abandoned them because of their single issue 100% or nothing stances. Don't think for a minute that the Republican powers in the Congress don't remember. They took a stand and when they turned around, noboby was standing behind them.
Based on what I have seen on this forum since the State of the Union Address, nothing has changed.
