The Rethugs are testing lines of attack against former VP Joe Biden and they don't appear to be working -- for now:
"Private Republican polling has shown Mr. Trump slipping well behind Mr. Biden in a number of key states. Perhaps just as troubling for Mr. Trump, it has raised questions about whether his efforts to tar Mr. Biden are making any headway.Be assured that Trump, having run an ultimately successful dirty campaign against Hillary Clinton, will try that approach again with Biden. But given Trump's manifest mental instability, disastrous handling of the coronavirus response, and swamp-level corruption, he has a record to defend, and the election will be a referendum on him.
Last month, a poll commissioned by the Republican National Committee tested roughly 20 lines of attack against Mr. Biden, ranging from the private business activities of his son, Hunter Biden, to whether Mr. Biden has 'lost' a step, a reference to mental acuity. None of the lines of attack significantly moved voter sentiment, according to two people briefed on the results. There were some lines of attack that had potential, one of the people briefed on the results said, but they were more traditional Republican broadsides about issues like taxes." (our emphasis)
It's all hands on deck to defeat Trump in November; no excuses.
