Did he really say that today? Do you have a link?
If he did, that's just an out and out lie (okay, misrepresentation of the truth). You don't become Al Gore's main guy in Texas in 1988 if that's true. Something isn't right here.
Wrong! So wrong! Perry was on record back in 2010 clearly stating that the last time he voted for a Democrat for president in the general election was in 1976 when he voted for Carter. He admits he was fooled by Carter - Southern Democrat, farmer, Christian - he though Carter was a conservative Dem.
Concerning working for Al Gore in 1988:
“[John] Sharp countered by noting that in the race for the Democratic presidential nomination in 1988, Mr. Perry was co-chairman of Mr. Gore’s Texas campaign. Mr. Perry acknowledged that but said there was a ‘push to get a conservative Southerner’ elected president.” (Sam Attlesey, “Link to Bush separates Perry, Sharp,” The Dallas Morning News, 9/15/98)
Sorry, the facts do not bear out your contention. Perry voted for Reagan twice and for Bush41 over Dukakis, all before becoming a Republican. He was a "Reagan Democrat", like so many other Southern Democrats. Now that you know the facts, I assume you will cease making this scurrilous charge and apologize.
