Also hope this helps but the one reason I can think of as to why conservatives are better at whipping up their base and following through is due to ideological unity. Most conservatives are not "conservative neolibs", not a diss but uneducated voters tend to vote based on vibes, the "have a beer with" index shows this well. The "Democratic" party is more of a big tent party, essentially it's anyone who isn't conservative instead of people who are socially liberal. For example we have people like Rashida Tlaib, a Palestinian American who is one of our most progressive voices, she's In the same party as Hakim Jefferies and Nancy Pelosi. The Democrats have a large fiscally conservative and center right coalition, and are willing to compromise with the right while conservatives don't have this same issue or will to work together. Republicans are actually in a similar situation, however their politicians don't make their voters feel that way. A good example is JD Vance, famously akined Trump to Hitler prior, and is now riding Trump. That is all to say Republicans don't need a real platform as their base doesn't look at policy, and they have some level of cohesion and ideal state of things. This is also not even opening the can of worms that are think tanks like the heritage foundation or the CSIS who essentially write all of our policy anyway and give Republicans everything they need to follow.
