That's quite convoluted, actually. Does "the buck stops here" ring a bell?
In 1992, Bush 41 lost votes that he won in 1988.
In one election he earned them, in another, he didn't.
Consequently, he lost the election to Clinton.Conclusion: Bush 41 lost to Clinton because his job perfomance was deemed by a significant portion of his earlier constituency to be insufficient cause to vote for his re-election.
I've got no personal stake in stating the facts here; I voted for President Bush in 1992, but it's no one's fault but his that he wasn't re-elected.
No one owes a politician their vote. You can complain all you want, but enough of the electorate realizes this, so our politicians are just going to have to listen and be accountable, or risk losing.
That's political reality, without the rationalizations or convolutions.
The GOP unable/unwilling to start at the grass roots level to change what voters don't like decided to engage in their own lazy form of self denial, giving the election to Billy-Bob.
