That may be their wish but it is usually frustrated by things like free speech and freedom of expression. Also the democratic process is generally more robust leading to a broadly consensus based political powerbase.
What we have instead is a questionable election result, heavily biased media and a single party in control now of all of the political houses in the US. The supreme court is apolitical of course and has a slim "Republican" advantage but the dems even have plans for that (pack the courts). They're also planning to introduce an extra couple of Democrat states to cement their position.
Meanwhile the propaganda arm of government (big tech) are systematically destroying any online presence that dares to voice dissent.
The danger is of course that while the Democrats may have carried off this incredible coup due to extreme circumstance (lack of support even from the Republicans for their own president and covid restrictions allowing a significant degree of rule bending), there is still the problem that at least half the country (!) do not actually support an extreme left wing agenda.
There may be trouble ahead.
