Unlikely.
While it is technically possible that the R's will retake both House and Senate, something would have to be going very badly at the time for a Republican sweep of all 3 including the Presidency. To be sure, it is a high enough probability that investors should not ignore that it COULD happen, it has short odds.

Also, the politics of voting against a new program are very different than those of taking an existing program away. In particular taking away a program that is responsible for thousands of high paying jobs, significant local tax revenue, and building cutting edge manufacturing facilities IN YOUR HOME STATE. Even if a thin margin exists in both houses (best case scenario outside great depression level event in US) the bill would lose at least a few votes in states like Texas, Tennessee, South Carolina, etc.

Keep in mind it would be nearly 24 months from now at the earliest and many of these projects will be funded by the LPO, have factories already built, and be beginning the product ramps in many cases. A unanimous rug-pull would be shockingly bad politics
