During his 2008 campaign, Barack Obama was like a mixture of the Teletubbies, a Hallmark card, and Morgan Freeman's portrayal of God in Bruce Almighty all mixed up in one big fruity glass. Every time you listened to the guy it was "hope" this, "change," I love "unity," "we are the ones we've been waiting for," and creating a "new tone" in D.C. That strategy turned out to be plausible because Bush was so unpopular and Obama's entire career consisted of getting elected to office and moving on before he had time to accomplish anything. That allowed Americans to see what they wanted to see instead of the real Barack Obama.
Since then, the American people have gotten an opportunity to see Barack Obama perform up close and personal in the world's most high profile job and they've found out the reality isn't much like the pretty picture the media and Obama's teleprompter painted for them in 2008. Barack Obama is not a nice guy, a genuine fellow, or someone you'd enjoy going to a ballgame with. He's everything people hate about politics personified: He's a nasty, habitually dishonest, hyper-partisan extremist whose entire strategy seems to be to drag the country off to the left while he blames other people for his failures and pits Americans against each other as much as possible. Comparing him to Nixon is even a bit of a stretch in that Tricky Dick may have been a son-of-a-b*tch, but he was at least a bipartisan and competent son-of-a-b*tch, which is something you can't truly say about Obama. There are, however, a lot of other points of comparison.
1) President "punish our enemies:" On Univision radio, Barack Obama actually referred to Republicans as "enemies" of Hispanic Americans,
And if Latinos sit out the election instead of saying, we're gonna punish our enemies and we're gonna reward our friends who stand with us on issues that are important to us, if they don't see that kind of upsurge in voting in this election, then I think it's gonna be harder - and that's why I think it's so important that people focus on voting on November 2.
You could say that the President of the United States telling an entire ethnic group that an opposing political party is its "enemy," like Al-Qaeda, because they don't agree with his political stance represents a "change in tone," but it's a change for the worse.
