GOP ramps up involvement in 2024 Senate primaries while Democrats stay out

Senate Republicans are endorsing candidates and influencing primaries to get more electable candidates unlike previous cycles.
Steve Daines is leading the strategy shift by endorsing candidates in states like West Virginia and Montana.
The NRSC is intervening more in primaries to avoid far-right candidates that may be unelectable in the general.
In contrast, Democrats are avoiding primaries and focused on protecting vulnerable incumbents.
Key Senate battlegrounds to watch include West Virginia, Ohio, Montana, Arizona, Nevada, and Wisconsin.
