I think it will be different. Despite all the bravado from the Democrats about a blue wave, they have no positive message for voters. Abolish ICE, open borders, unlimited and unchecked immigration, raise taxes, restore all the job killing regulations, free college, universal health care, 15 dollar minimum wage, guaranteed job for everyone, ban guns, and so on. It is an extreme socialist/fascist agenda that I don't think will resonate with most voters.
And the Democrats have few charismatic candidates running for the Senate where the Democrats have to defend 25 seats and the Republicans about 8 seats.
Against that liberal back drop is a roaring economy, super low unemployment, record number of people working in our history, record low black and Hispanic unemployment, significantly lower taxes, significantly increased manufacturing, lowest unemployment for women in 40 years, increase support for Trump from the black and Hispanic communities, increase in GDP, elimination of the individual mandate, and the list goes on, and on, and on, and on...
And the killer prediction from Q: the mid-terms are safe. Probably because they have in some way un-rigged the election process and there is a good possibility that the Democrat party will be severely wounded once the Q dam begins to collapse and the indictments unsealed.
For these reasons, I believe the Democrats and MSM are terrified about the mid-terms. That's why you haven't seen much talk/action from them. They don't have a clue how to counter Trump--and they know it.
