This is how it works:
Scenario 1: A Republican presidential campaign gets dirt on their political opponent from foreign sources, so investigate the Republican candidate and his campaign for colluding with a foreign power to sway an election.
Scenario 2: A Democratic presidential campaign gets dirt on their political opponent from foreign sources, so investigate the Republican candidate and his campaign for whatever the alleged crimes are.
You clearly have not been paying attention
Your Scenario 1 would be all good if your facts were correct and accurate. Let me rephrase your scenario 1 with facts that accurately reflect reality.
Scenario 1: A Republican presidential campaign gets dirt on their political opponent from a hostile foreign sources Government, and continues to co-operate with that hostile foreign Government to the tune of over 120 individual, documented and verifiable contacts by over 20 members of the campaign, so investigate the Republican candidate and his campaign for colluding with a foreign power to sway an election.
Your scenario 2 fails completely because you are missing keys facts, or have made up untruths and purported them to be facts. Let me rephrase your scenario 2 with facts that accurately reflect reality.
Scenario 2: A Democratic presidential campaign gets dirt intelligence on their political opponent from a private, non-Government foreign source, a citizen of a friendly, allied country. Further, the intelligence provided was very troubling and showed a high possibility that the Republican presidential campaign was in fact colluding with a hostile, foreign Government to sway the election, so investigate the Republican candidate and his campaign for whatever the alleged crimes are for colluding with a foreign power to sway an election.
p.s. The Mueller report is the prosecution side and was written by partisan Democratic hacks.
Robert Mueller III, a lifelong Republican, a man who is scrupulously unbiased, who headed the FBI for 12 years after a bipartisan 98-0 Senate confirmation, who served under both Republican and Democratic Presidents, will be shocked to find out that he is a "partisan Democratic hack"
I have come to the conclusion (and I am sure many others here will have reached a similar conclusion) that you have absolutely no ******* idea what you are talking about.
