Given that the Democrats include significant leaders who are openly anti-Semitic, and the party is increasingly anti-Israel, and supports many policies that would seriously hurt the frum community, there isn’t much choice. If the Democrats returned to the leaders in the mold of John Kennedy, Skip Jackson, Joseph Lieberman, Harry Truman and Hubert Humphrey, it wold be different. But the Democrats have “evolved”, which is why many Republicans (e.g. Ronold Reagan, Donald Trump, et al,) are former Democrats.
Based on public information, it is clear that Trump was justified in demanding the Ukranians investigate corruption that took place during the Obama administration, which accepted bribes from Ukraine. It also appears that the Democrats colluded with Russian intelligence to spread “fake news” defaming Trump, and lied about it in order to get the a federal court to authorize otherwise illegal political espionage directed against the Trump campaign. In other words, so far the evidence is that Obama was guilty of high crimes.
