David Limbaugh:

Their unhealthy hatred for Mr. Bush dates back to the 2000 election, which they -- irrationally again -- believe he stole from Mr. Gore. The fact is, Mr. Gore was trying to steal the election himself and almost succeeded, through one of the most egregious perversions of the rule of law in our nation’s history, by the Florida Supreme Court.

But the real source of their animus is even more basic. They resent him because he represents their expulsion from power over the executive branch, which the Clinton eight-year heyday should have ensured them in perpetuity.

You’ll recall that their "entitlement" to the legislative branch was stolen from them in 1994, which is one of the reasons they consider Newt Gingrich another personification of evil. Adding insult to cumulative injury, they’ve also lost their monopoly on the media over the last 15 years.
