Blue Rectangle:
Nixon and Bush 1 were moderates who did some good things such as environmental protection and the hate crimes bill. George W. has never done a single thing to reach out to moderates or Dems, 100% of his legislation is aimed at the far right of the party.
And neither Bush I nor Nixon ever got an ounce of credit from the Democrats for their "moderate" policies. I see a lot of Democrats praising Bush I, but trust me, not a single one of them would have supported him when it counted - in the voting booth. So that tends to throw that political strategy into question because the job of a politician, after all, is to win elections.
