A quick look at their record will answer this question. forty years of the conservative agenda and the country has had only one little spurt of progress when a Democrat was president. Other than that a consistent record of failure. Economic growth during the Reagan and Bush administration that was supported by borrowing and record setting debts. Reversal in our decline in poverty every time a Republican was president, Increased unemployment every time a Republican was president, Decline in manufacturing every time a Republican was president....Now there only hope that they can force a Democratic administration to be the total failure they were. So for, they haven't been too successful and last month the Obama administration added more private sector jobs than Bush did for his entire first term, the stock market keeps plugging along, manufacturing has increased and they have been successful only in stalling Democratic proposals.
EDIT: Reality check for @Galaxy being...In 2006, the economy was not "humming along." The stock market was up, but the entire economy was a house of cards built on an extrodinary amount of borrowing both private and public. Both privater debt and the national debt were at record highs. The unemployment was good, but it was also up from when the 3.4% Bush inherited from the Clinton years. Republicans took office and for four years the Bush administration did not have a net gain in private sector jobs (ended the first term with an administration that had not recorded an increase in the number of jobs for the first time in history and finished two terms with a net increase of only 2 million jobs...again, worst performance in history) Hard to put this on a little more than year of Democratic control of congress...especially in the light of the fact that George Bush recorded a record number of vetoes in that year and a half after having completely lost his "veto pen" for the first six years.
