Hand lettered.
Note that repeating letters _K_ and _E_ do not match.
Closest I found in a font to approximate I LIKE IKE is Benton Sans Black.
Note that the center stroke on _E_ is too short.

Franklin Gothic is also in the ballpark, but not as close.

Helvetica is also close but weight is wrong. Need something between Bold and Black to be a good substitute.

This should be good.

If I recall correctly the I LIKE IKE button was from the 1952 election.
Helvetica was designed in 1957 and did not offer a weight between bold and black, i.e. heavy.
Helvetica Neue Heavy [suggested by DimensionPizza] seems to be your best choice to recreate something close to the hand lettered I LIKE IKE.
Here is Helvetica Neue Heavy, with I LIKE scaled to 50% of IKE:

Thank you for all the reponse. I finally used Helvetica and it looks ok.
