Of course they will try again. Likely before the election while they still have a majority.
The Democrats have made no secret of this. They have bragged openly that they will impeach as many times as they have to.
Not necessarily with the idea that they will 'remove' Trump. It is more for harassment.
The more the Dems can keep Trump and his staff bogged down with frivolous 'investigations', the more they can disrupt his campaign and disrupt his ability to govern both domestically and internationally.
Also, it keeps him from investigating them, which is their primary concern. Harass, disrupt, impede, and distract, is currently the only known goal the Democrats have in life. Their whole entire life right now is only about interfering with President Trump in any way they possibly can.
