I don't know which Obama you were watching, but it wasn't Barack. Not only did he NOT reach across the aisle, he shunned the Republicans during his tenure. Don't you remember his snarky comment about "elections have consequences". In fact, he hardly worked with the Dems in Congress either. Remember "I've got a pen and a phone". He ruled through Executive Orders, rather than trying to get legislation passed through Congress.
The only major legislation that Obama got passed through Congress was Obamacare and he had to lie like Hell to get that through, even though he had a super majority in the House and the Senate. Dems keep complaining about the bad deal the DACA kids are getting, but rather than fix the problem legislatively then, they decided it was more politically advantageous to keep the issue and use it against the Republicans. It's hard to see past the hypocrisy, when the Dems bring up the plight of the poor DACA kids.
Obama was divisive and he probably set race relations back 20 years, during his time in office.
Trump is rude and crude, but he's getting things done, in spite of the obstruction from ALL the Dems and a lot of the establishment Republicans. Trump has been his own worst enemy for the majority of his time in office. He would do a couple good things and then step all over them by saying or tweeting something stupid. The media would focus on the dumb comment and he got no credit for his achievements. It's times like that that you realize he's NOT a politician. Many times I've wanted to reach into the TV and slap him, when he said ridiculous things, but I'm past that now. I've learned to filter out the BS and concentrate on results. So far he's delivering on his campaign promises..
Obama was smooth and articulate, but he was corrupt. The first he heard about "Fast and Furious", which was being run out of his Justice Department, was when he saw a media report about it. Sure. He weaponized the IRS to stifle Conservative groups from getting tax-exempt status in the years leading up to his reelection run. When asked about it, Obama said there wasn't a scintilla of corruption in the IRS. We lose an Ambassador and 3 others in Benghazi a couple months before Obama's reelection run and he and Hillary make up this ridiculous story about the Libyans being upset about a video and having a spontaneous riot. I guess it's better to lie to the American people and the families of the deceased, than to admit that Al Qaeda is still alive and killing Americans. Then he weaponized the Justice Department and the FBI to protect Hillary and destroy Trump. And the MSM downplayed all of it, because they loved the guy.
You can forgive all that, yet you can't forgive Trump for being crude. Did you forgive Bill Clinton for turning the Oval Office into his own private Bordello and all his other sexual misconduct? Of course you did, because he has a D after his name.
