What do you think the Founding Fathers would think of abortion?

[Thomas]

Discuss your opinions, Like Washington,Jefferson, Franklin and etc.

[100% pro-life no matter what]

They would look at it with absolute horror

[America Needs R'hllor]

They would look at it with absolute horror

Just like many of them would look at abolition of slavery (or civil rights generally), gay rights, even suffrage.
What people, no matter how brilliant, thought centuries ago is no indication for what's right.

[I spent the winter writing songs about getting better]

Seeing as early termination of pregnancy occurred at the time and wasn't really controversial they'd probably all qualify as pro-choice. Even the Roman Catholic Church didn't oppose abortion until the mid-19th century.

State issue. Certainly not a federal constitutional right, other than congress lacking an enumerated power to regulate it.

What would the founding fathers think of civil rights?

What people, no matter how brilliant, thought centuries ago is no indication of what’s right.

Their thoughts, centuries ago, matter if and when we are interpreting a law that they made. For example, what would the expression "a wall of separation between church and state" have meant to our Founding Fathers?
However, since they did not make any law about abortion -- not enacted into the U.S. Constitution -- then the correct answer to the OP is:

State issue. Certainly not a federal constitutional right, other than congress lacking an enumerated power to regulate it.

[OSR stands with Israel]

Lol no

[Unconditional Surrender Truman]

[Middle-aged Europe]

I guess they would have been split right down the middle on this issue.

Abortion was generally considered a crime in the common law from the time of "quickening" (i.e. when a woman would be able to feel the movement of the child in the womb).  States began also prohibiting abortion by statute in the 1820s, though it was rarely prosecuted.

[Goldwater]

They would have the same position as me, obviously.
