I want to know the answer to the following question:
Why could the Tories and the Opposition Whigs never form a single party?
All the background I'm provided with is that "Although the Tories were dismissed from office for half a century, for most of this period (at first under the leadership of Sir William Wyndham), the Tories retained party cohesion, with occasional hopes of regaining office, particularly at the accession of George II (1727) and the downfall of the ministry of Sir Robert Walpole in 1742.". Is that enough to answer the question?
Answer: no
