1. Unlike the Republicans (with the exception of Liz Cheney and Adam Kinzinger), the Democrats will fully participate in the GOP House hearings. The Dems will be asking half the questions. The Dems will use humor to point out hypocrisy to undermine the GOP efforts to prosecute the Bidens.
2. In the J6 hearings, the Dems went to great pains not to have the hearings appear partisan. The witnesses were Republicans and/or former members on the Trump staff and administration.
3. J6 was a not a hearing looking for a crime. The crime was an attempted coup. The criminal insurrectionists' attack on the Capitol was obvious. Undo influence on state level election officials by Trump allies was well established. In contrast, the Republicans will be searching for a crime that they hope to pin on Joe Biden.
4. The GOP House will spend a lot of time on pseudo-scandals: Hunter Biden doing drugs, Hunter Biden naked, etc.
5. The GOP House will embarrass themselves with their own hypocrisy. They will attempt to turn Hunter Biden's ethically-questionable choices into a crime. They will decry nepotism. All the while swearing fealty to the criminal enterprise known as the Trump Family. The media will report on GOP House member's family members with lucrative government contracts and cushy government jobs.
6. Unlike the J6 hearings which were about a crime against America and peaceable transference of power, the House will be investigating a private citizen. They will be outraged by Hunter Biden's tax avoidance all the while being oblivious to the Trump Organization being found guilty of 17 counts of tax fraud.
7. Republicans will demonstrate their misunderstanding of the First Amendment by whining about Twitter, a private business, and their decision to not run the Hunter Biden's laptop story. The Wall Street Journal made the same editorial decision.
8. The Republican hearings won't have the same high quality production values as J6. I will be surprised if any are aired in prime time. Expect to see a lot of Coatless Jim Jordan interrupting witnesses and pounding the table.
9. Republicans will whine that their hearings aren't getting the same sort of media coverage and Nielsen ratings as the J6 hearings.
10. The Democrats will get as many or more of the sound bites that airs in newscasts. In other words, the GOP will lose control of the narrative. Not surprising as the GOP goals were vague in the first place.
11. The GOP House hearings will have a farcical vibe. The ensuing lack of respect will drive MAGAites nuts.
