Democrats do anything to win. Lie, cheat, steal, voter fraud, recounts, invasions of privacy, obfuscation, misuse of the criminal and civil legal system to destroy opponents, trumped up false witnesses for character assassination - absolutely anything, whether legal or moral.
And Democrats stick together. They will ALWAYS support the illegal and immoral activity of another Democrat to propagate their vile agenda. No deviance is too repulsive and no crime too heinous if it causes a fellow America hater to win.
Conservative Republicans cannot habitually lie, cheat, or steal without becoming Democrats.
The Democrats have always had a vastly superior ground game, at least has far back as I can remember.
It helps tremendously when you have an army of PAID union workers to help get out the vote on election day, whereas the GOP has to rely primarily on volunteers to help with its GOTV efforts.
It helps when you have the public school teachers, college professors, most of the media, and the entertainment community on your side and most of the billionaire political fundraisers on your side. The Dems win overwhelming in all of the richest zip codes in this country.
Further, the Dem vote in this country is highly concentrated in dense urban areas. Many of the precincts in these areas have few, if any Republicans, and there is little or no bipartisan oversight supervising the voting in these precincts. And of course lax or no voter ID laws in most of the blue states.
In addition most of the big cities are run by Democrat political machines which work hand in glove with unions getting the vote out and with so little GOP representation in most of our inner cities, there are endless opportunities for cheating and fraud in these one-party strongholds.
