Democrats currently running for president are making great political ads for Trump...

... and republicans to use, and they are doing it for free!
It doesn't matter who our nominee is, all republicans have to do is post videos of our candidates making charges against the eventual nominee during the primaries. Some of the charges that have been made are shocking if true. Undecided independents and republicans would likely have doubts if the nominee is fit to be president. IMHO.

1. In itself, that isn't unusual

At some point a candidate gets down to “this is the end unless something changes” - and that’s when they pitch that picking the other guy could mean losing the election.

That’s part of the vetting process too. It isn’t as though Trump is learning lanes of attack that he wouldn’t otherwise use.

2. This has always been done.

3. If Sanders is the nominee they won't need anything from the debates

It will be month after month of Daisy caliber stuff, but without public rejection

4. Trump did not let that stop him in 2016. We can be just as bold+more honest

After we have a nominee, the other candidates can each do a joint ad with the nominee.

If we engage in too much self censorship in our primary phase don't get ahead of what will be thrown at the nominee by the Republican Party in the general election. They will have oodles of opposition research on the nominee-best if it is not a surprise and a shock to voters.

5. This is standard for elections

nothing any of our Dems have on them would be as shocking as what Trump has done over and over and over again.

6. People pay less attention to old news

So it’s best to get it all out now so by the time the republicans run with it it’s old news

7. I have absolute confidence that the reTHUGS are capable of developing corrupt political ads

with or without any input from Democrats. No pearl-clutching over this for me.
